Could anyone give me some direction on how to more accurately track my sugar intake with FitDay's daily food log? I love adding in all my custom foods, but I've always been curious why there isn't a "sugar" amount column in addition to the other options (i.e., carbs and alcohol, etc).

Don't know if this helps but Sugar is a simple carbohydrate so it is included in your carbohydrate count. Many track 'Net Carbs' which are your total Carbs minus the fiber thus basically giving the simple carbs. (Complex carbs are just simple carbs with fiber.) So you can look at net carbs as being equivalent to sugar.
